(Cl. l-149)The present invention relates in general to a pocket door frame adaptedto be built into a wall, or the like, adjacent a doorway and adapted toreceive and conceal a sliding door when the latter is in its openposition.

More particularly, the invention relates to a xture or jig forassemblying pocket door frames quickly and easily from prefabricatedparts.

As background, the portion of a pocket door frame to be assembled in thejig of the invention includes: a back or bumper jamb; two sets of pairedhorizontal spreaders embracing and extending perpendicularly from thebumper jamb and having ends abutting and secured to opposite sidesthereof; two channel-shaped split-jamb stilfeners telescoped over theoppoiste ends of the spreaders of the respective sets; and two splitjarnbs abutting the respective stifleners substantially in alignmentwith the spreaders of the respective sets, the split jambs and theirstiifeners being secured to the spreaders. As a sliding door used withsuch a pocket door frame is opened, it moves between the split jambs andtheir stiieners into the space between the two sets of paired spreaders,opening movement of the door being limited by engagement with a bumperor the bumper jamb.

A pocket door frame of the foregoing nature is, of course, installed inan upright position with the bumper and split jambs substantiallyvertical. However, the jig of the invention assembles the pocket doorframe with the frame rotated approximately 90 into a position whereinthe bumper and split jambs are generally horizontal and wherein thebumper jamb is below the split jambs. For terminological convenience,the ends of the bumper and split jambs and the ends fo the split-jambstifeners which are lowermost when the pocket door frame is upiight, andthe edges of the spreaders which are lowermost under such conditions,will be referred to as their lower ends and edges, respectively, evenwhen the pocket door frame is oriented generally horizontally in the jigof the invention.

The invention contemplates, and general objects thereof are to provide,a pocket-door-frame assembly jig which includes: an upright supportingstructure; a generally horizontal lower positioning means mounted on thesupporting structure and having means for supporting the bumper jamb andone end of each of the spreaders; locating means on the lowerpositioning means and engageable with the edges and one end of thebumper jamb and with one edge of each spreader for locating the bumperjamb and the one end of each spreader in assembled relation; a generallyhorizontal upper positioning means mounted on the supporting structureabove the lower positioning means; a plurality of spacer means on theupper positioning means and each engageable by adjacent sides of thespreaders of one pair adjacent the other ends thereof to space sameapart; and a plurality of pairs of holding means on the upperpositioning means for holding the respective pairs of spreaders againstthe spacer means, respectively.

An important object of the invention is to provide a jig of theforegoing nature wherein the holding means for holding the respectivepairs of spreaders against the respective spacer means comprises pairsof spring clips or spring clip means which resiliently clamp thespreaders against the spacer means. With this construction, thespreaders are automatically held in place against the spacer means,which are preferably spacer blocks, upon insertion into thecorresponding clips, which is an important feature.

Another important object is to provide a jig of the character outlinedwherein the locating means mentioned is engageable by the lower end ofthe bumper jamb and the lower edges of the spreaders, the lower ends ofthe split jambs and their stifeners similarly being engageable with anend stop or stop means on the upper positioning means. With thisconstruction, the positioning of the various parts of the pocket doorframe is eected with reference to the lower ends or edges of the variousparts, as opposed to the upper ends or edges thereof. Consequently, thelower edges of the spreaders of the lowermost pair are automaticallypositioned flush with the lower ends of the bumper and split jambs andthe split-jamb stilfeners, a positional relationship which is standardin a pocket door frame of the type under consideration. This standardpositional relationship is automatically achieved with the jig of thepresent invention despite Width variations in the spreaders of thelowermos pair, which is an important feature.

Another object of the invention is to provide a jig which may be used toassemble pocket door frames of various Widths by providing means formounting the lower positioning means on the supporting structure of thejig various distances below the upper positioning means, the latterremaining Xed.

Another object is to provide a jig which is a self-oontained,free-standing unit requiring no supporting means other than thesupporting structure and the upper and lower positioning meansmentioned. A related object is to locate the various parts of the jigwhich engage the various parts of the pocket door frame forwardly of theupright supporting structure for the upper and lower positioning meansso that, upon assembly, the finished pocket door frame may be removedfrom the jig readily without interference by the upright supportingstructure and without any necessity for removing any parts of the upperand lower positioning means, or for any auxiliary supporting meanstherefor.

Another object of the invention is to provide a jig Wherein the upperends of the spaced blocks are recessed to permit insertion of theadjacent flanges or ange portions of the channel-shaped stifrenersbetween the spacer blocks and the corresponding spreaders. Thisconstruction permits the spring clips to maintain the spreaders clampedagainst the respective spacer blocks even after the stifteners aretelescoped over the corresponding ends of the spreaders.

A further object is to provide means on the upper positioning means forretaining the split jambs in their assembled positions on theirstitleners and respectively adjacent opposite sides of the spacerblocks.

Still another object of the invention is to provide a jig wherein thestop means engageable with the lower ends of the split jambs and theirstilfeners is movably connected to the upper positioning means so thatit may be moved aside to permit the attachment of a split-jamb spacer tothe lower ends of the split jambs prior to removal of the assembledpocket door frame from the jig.

Another and important object of the invention is to provide a jig havingstaple-gun locating means thereon at all locations where staplingtogether of various parts of the pocket door frame is required, suchlocating means automatically positioning a staple gun correctly for thevarious stapling operations required.

The foregoing objects, advantages, features and results of the presentinvention, together with Various other objects, advantages, features andresults thereof which will be evident lto those skilled in the art towhich the invention-relates in the light of this disclosure, may beachieved with the exemplary embodiment of the invention described indetail hereinafter and illustrated in the accompanying drawings, inwhich: A n y FIG.' 1 isa top plan viewl'ofra pocket-door-'frame assemblyjig of the invention; 1 i

Referring initially to FIG. 3 of the drawings, illustrated therein is aportion of a pocket door frame ito be assembled by the inventionf Theframe lo'includes a vback or 'bumper jarnb 12 having' a plurality ofpairs of horizontal spr'eaders 14, secured thereto in vertically spacedrelation. The spreaders 14 of each pair receive the bumper jamb 12therebetween and respectively/abut and are secured to opposite edgesthereof. Telescoped over the opposite endsv of the respective s ets ofspreaders 14, i.e., the two spreader sets on opposite sides of thebumper jamb 12, are laterally spaced, channel-shaped split-jambstiffenersY 16, preferably of metal. Abutting the respective stiffeners16 substantially in alignment with therespective sets of spreaders 14are splitl jambs 18, the respective stifeners and split jambsVbeingsecured to the spreader sets.'` The various parts are securedtogether by nailing, stapling, or the like.' Stapling will be consideredY hereinafter vwith the understanding that an equivalent fasteningtechnique may be used. To maintain the lateral spacing of the splitjambs 18 Vduring handling, shipment, and the like, temporary spacers 20are secured' thereto in any suitable manner, as by stapling.

The jig of the invention for assembling the pocket door frame 10designated generally by the numeral 22 Yand is so oriented that itassembles the. pocket `doorjframe with Y the latter rotatedsubstantially 90 into a generally'horizontal position, wherein thebumper jamb 12 is below the split jambs 18.

The jig 22 includes an upright supporting structure shown as consistingof two horizontallyspaced uprights 24 having suitable bases 25.Mountable on the uprights 2e invarious vertical positions is a4generally horizontal lower positioning means 28.' The purpose of makingthe .lower positioningV means 28 mountable on the uprights 2.4. invarious vertical positions is to accommodatepocket door frames ofdilferent widths. The lower positioning rneanS 28; may be securcd'to theuprights 24 in various ways, as by bolts secured bywheel nuts'S, FIQJ.

As will be described, the lower positioning means 2S properly positionsthe bumper jamb 12 and the ,corre spending ends `of the spreaders '14.The opposite ends of the spreaders 14, thestitfeners 16 and the splitjambe 13 are all properly positioned by agenerally horizontal upperpositioning means 32'permane'ntlyY secured to the uprights 24.

The lower positioning means 28 comprisesV a member 34 having a flat topsurface 36 which serves as a'rneans for supporting the bumper jarnb 12and the adjacent ends of the spreaders 14. Provided on the top surface36V of the member-34 are locating means 'engageable with the edges andthe lower end of the bumper jamb 12 and with-.the lower edges of thespreaders 1d for properly locating the-bumper jarnb and the adjacentends of the spreade'rs relative to each other.

The aforementioned locating means includes an end stop 33 at one end ofthe member 34 and engageable by the lower end of the bumper jamb V12 andby the lower edges of the lowermost spreaders 14, as shown in HG. 2 ofthe drawings. With this construction, the lower edges of the lowermostspreaders 14 are iiush with the lower end of the bumper jamb 12irrespective of the of the drawings. Thus, the V'stops 3S and i0 serveto properly locate the bumper jamb and the corresponding ends of thespreaders 14 relative'to each other. i

The positioning means 32 includes a "horizontal bar 42 secured to theuprights 24 adjacent their upper ends. Projecting forwardly from thebar'42 are brackets 44 carrying spacer means or blocks 2,46 for spacingapart the stifeners 16, the split 'jambs 18 and the corresponding endsof the spreaderslkt. Also secured to the brackets '44 and embracing therespective blocks 46 are U-shaped spring clips or spring clip means FIG.1 each having two arms lrespectively adapted to clamp the respectivespreaders 14 of the corresponding pair against opposite sides of thecorrespondingblock lt will bev understood, of course, that'tne blocks inand spring clips d8 are so located relative tothe stops $8 and@ on themember 34 that when the spreader ends 'associated with the bumper Yjarnbv12 are properly positioned, the spreader ends associated with' the'split jambsv are clamped against the blocks le by the spring clips 4S.Also, when therspreade'rV ends associated withthe vsplit janibs 1S are,inserted all the way into the respective spaces between the blocksAnand the arms of the spring clips ed, the lower edges thereofengage'theconnecting portions of the spring clips to properly locate thespreader vends in question relative to the split jvambs 18 and thestiffeners 1d therefor.

The bracket i4 which is located at the same end of the jig 22 as the endstop 33 carries an end stop dtl'engageable by the lower ends of thes'tifeners 16 and the split jarnbs 18 and located in the same verticalplane as the end stop 33. rthus, the lower end of the bumper jamb 12,the lower edges ofthe spreaders 1d* of the lowerrnost pair, and thelower ends of the stiieners 1d and the split jambs 1S are 'all iiu'sh`when these parts of the pocket door frame 1? are placedin the jig 22.

As shown in FIG. foot the drawings, the end stop SQ is mounted on apivot 52 so that it may be swung aside for access tothe lower ends ofthe split jambs 18 and the lower edges of the corresponding spreaderends. permits nailing, or otherwise securing, a jamb spacer, not shown,to vthelowerends of the Vsplit jarnbs 18 and the corresponding spreaderends of the lowerrnost spreader pair. Such a jamb spacerV is normallysecured after the bumper jamb 12, spieaders 1d, stiffeners 16 and splitjambs 18 have' been assemble/din a manner to b e described.

Asbest shown in FIG. 4 of the drawings, the sides of the spacer blocksd6 which are engageable by the corresponding spreader ends are providedat their upper ends with recesses Se to permit the insertion ,ofV thecorresponding flange portions of the stiifeners 16 as such stiifenersare telescoped over the corresponding spreader ends.

At least one of the brackets td-carries a bracket 55 having supports 56for the splitjambs Vwhen they are placed on the stiffeners 115,A asshown in 4 of the drawings, and, which keeps' there from falling @if thestitieners priorv to securement. While only one of the splitjambsupporting brackets 5 5 kis shown, it will be under- The.

may be placed anywhere without any necessity for any auxiliarysupporting means. All that is required to ready the jig 22 for use is toplace the lower positioning means 2S in the proper vertical position forthe particular pocketdoor-frame width to be dealt with, if it is notalready in such position.

ln assembling the pocket door frame 10, the first step is to place thebumper jamb 12 on the top surface 36 of the member 34 between the tworows of stops 4t? and with its lower end against the end stop 38. Thespreaders 14 are then placed in the jig 22'. with one end of eachresting on the top surface 36 of the member 34 in engagement with thecorresponding one of the stops 38 and 4t) and the corresponding edge ofthe bumper jamb, and with the other end thereof inserted all the wayinto the space between the corresponding spacer block 46 and spring clip48. The spring clips 43 automatically hold the spreaders 14 in theircorrect positions. Then, the stilieners 16 are telescoped over therespective sets of corresponding spreader ends and the split jambs 18are placed on the respective stiteners, the lower ends of the stiienersand split jambs being seated against the end stop Si), which is in itsclosed position under such conditions.

It might be pointed out at this juncture that since the various partsare located relative to each other in the foregoing manner using theirlower ends of edges as reference points, the jig 22 is readily useablewith pocket door frames 1) of diterent heights. With a frame of greaterheight, the upper ends of the bumper jamb 12, the stieners i6 and thesplit jambs 18 merely project farther to the right, as viewed in FIG. 2of the drawings.

With the bumper jamb 12, spreaders 14, stiffeners 16 and split jambs 18all properly located relative to each other by the jig 22 in theforegoing manner, all that remains to be done is to secure the variousparts together. This is preferably done by stapling, using a'conventional staple gun 5S, FlG. 4.

An important feature of the invention is that the jig 22 includesstaple-gun locaters in the form of pins 6d each receivable in a V-notch62 in a locating element 64 secured to the staple gun 58. Thus, byplacing the staple gun 58 in such a position that one of the pins 60 isseated in the V-notch 62, the gun is automatically located properly todrive a staple at the corresponding location. As best shown in FIG. 7 ofthe drawings, locating pins 6i) project laterally from opposite sides ofthe member 34 at the locations where staples are to be driven throughthe spreaders 14- into the bumper jamb 12. Similarly, locating pins di)project upwardly from the spacer blocks i6 at the locations wherestaples are to be driven through the split jambs 18 and stifeners 16into the spreaders 14. ln this connection, it might be pointed out thatthe stitieners 16 may either be provided with staple holes at the properpoints, or they may be made of sheet metal thin enough that the staplesmay be driven directly through the metal.

As will be apparent, as the result of the provision of the locating pins60, the various parts of the pocket door frame 1@ may be stapledtogether very rapidly with the staple gun SS. Preferably, the spreaders14 on both sides of the pocket door frame 16 are stapled to the bumperjamb 12 iirst. Then, the split jambs 1S and stifeners are stapled to thespreaders 14, the operator using one hand to clamp the split jambs 18against the corresponding sides or" the spacer blocks 46.

The foregoing completed, the temporary spacers 20 are stapled in placeand, if a jamb spacer at the lower ends of the split jambs 13 isrequired, this may be stapled or nailed in place very easily by swingingaside the pivoted end stop 5t?.

T he assembled pocket door frame 10 may be removed from the jig 22merely by lifting it slightly to clear the stops 49 and then sliding itto the right, as viewed in FIG. 2 of the drawings, until the spreaders14 disengage CII 6 the spring clips 48. The completed frame 10 is thenfree to be lifted clear of the jig 22.

Although an exemplary embodiment of the invention has been describedherein for purposes of illustration, it will be understood that variouschanges, modifications and substitutions may be incorporated in suchembodiment without departing from the spirit of the invention as deiinedby the claims which follow.
